Whenever I run regular mp4 avi files (which don't require transcoding), they work flawlessly. But, as soon as I try to use subtitles (SRT files), they take a long while to start on the PS3, start off slowly (low fps) and then go into hyper mode: they go really fast...these aren't HD files and usually have a ~1.0-2.0 Mbps rate but when I use SRT files, PS3 shows the bitrate going around 30-40Mbps with the video going really fast. Also, the SRT files aren't synced with the video at all. Also, I'm not really that great with playing around with options and codecs so if there is a suggestion that requires more than just tinkering with the settings, please provide step by step instructions. Thanks.
